Ingredients for Marshmallow Crisp Microwave Rice Krispies Squares

  • 1/4 cup (1/2 stick) unsalted butter
  • 4 cups of mini marshmallows (or 10 oz bag of large marshmallows)
  • Crispy Rice Cereal

How to Make Marshmallow Crisp Microwave Rice Krispies Squares

  1. Butter a small (approximately 8x8 inch or 9x9 inch) oblong baking pan.
  2. In a large, microwave-safe casserole dish with a lid, melt 1/4 cup (1/2 stick) of butter in the microwave on high for 1 minute. Stir if needed.
  3. Add 4 cups of mini marshmallows to the melted butter.
  4. Cover the casserole dish and microwave on high for 2 minutes.
  5. Remove, stir, then cover again and microwave in 30-second intervals until the marshmallows are completely melted and smooth. (Total microwave time will likely be around 2-3 minutes).
  6. Stir until the marshmallows are completely melted and well combined.
  7. Add 5 cups of Rice Krispies cereal and stir gently until the cereal is evenly coated.
  8. (Optional: Add 1 cup of chocolate chips or M&Ms at this stage and stir to combine)
  9. Lightly wet your hands and press the mixture into the prepared pan.
  10. Allow to cool and set completely before cutting into squares.
  11. Store covered tightly to maintain freshness.

Chef's Tip for Extra Flavor

Chef's secret: layers of flavor make a dish truly memorable! Consider what a little extra something could bring – perhaps a touch of acidity like a good vinegar or citrus zest, a hint of smokiness from paprika, a bit of umami from mushrooms or soy sauce, or a sprinkle of toasted nuts for texture. Experiment and taste as you go!
